Book Synopsis Numbers of Calling Whales in the North Pacific by : William A. Watkins
Download or read book Numbers of Calling Whales in the North Pacific written by William A. Watkins and published by . This book was released on 2001 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since November 1995, the U.S. Navy's Sound Surveillance System (SOSUS) and other hydrophone arrays were used to regularly sample the occurrence of whale sounds in four regions bordering the continental margins across the North Pacific. The numbers of whales heard calling varied with season and location for each species, blue whales (Balaenoptera musculus), fin whales (Balaenoptera physalus), and humpback whales (Megaptera novaeangliae). For blue whales, calling during the fall season averaged 5 whales per event, winter averaged 1.5 whales per event, spring averaged 1 whale, and summer averaged 1.5 whales. For fin whales the numbers of whales heard ('F' calls from individuals) during winter averaged 3 whales per event, spring and fall calling averaged 1.5 whales, and summer averaged 1 whale. The 'J' calling events, regardless of season, were judged to be from at least 6 fin whales. Humpback singing typically was from 3 whales. These number demonstrated seasonal variations in calling whales for each region.

Download or read book Distribution of Calling Blue, Fin, and Humpback Whales in the North Pacific written by and published by . This book was released on 2000 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seasonal distribution of calling blue whales (Balaenoptera musculus) and fin whales (B. physalus), and singing humpback whales (Megaptera novaeangliae) has been analyzed from acoustic data recorded by U.S. Navy Sound Surveillance System (SOSUS) and other hydrophone arrays in the North Pacific. The data from ten arrays were selected as representative of four Regions along the continental margins, labeled Northwest (NW), Northcentral (NC), Northeast (NE), and Southeast (SE). The call data indicate that there is a substantial population of blue whales scattered over the North Pacific and concentrated during the Fall season in the NW and NC Regions. Blue whale calls are recorded in all seasons, particularly in these NW and NC Regions. Fin whales are found in groups but also in relatively large numbers in all Regions, with most calling in the Winter season and in the NC Region, and calling is absent in most Regions during Summer. Fin whale calling includes "F" calls from individuals heard in all seasons and "J" calls from too many whales to separate, particularly prominent in the winter reproductive season. Humpback singing is recorded most in the NC and SE Regions at the time of their Winter/Spring migration. The distribution of singing humpbacks changed in both the NC and SE Regions between the 1996-1997 and 1998-2000 periods.

Book Synopsis Listening in the Ocean by : Whitlow W. L. Au
Download or read book Listening in the Ocean written by Whitlow W. L. Au and published by Springer. This book was released on 2016-02-25 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: This title brings to light the discoveries and insights into the lives of many marine species made possible over the last decade by passive acoustic recorders (PAR). Pop-ups, ARF, HARP, EAR, Bprobe, C-POD Atag, and Dtag are the acronyms of some of the many PARs that have changed our understanding of how marine animals live and strive in the ocean. Various types of PARs are used by different investigators in different areas of the world. These recorders have accumulated copious amounts of very important data, unveiling previously unknown information about large marine animals. Temporal, seasonal and spatial distribution patterns have been uncovered for many marine species. There have been many discoveries, new understandings and insights into how these animals live in and utilize the ocean and the importance of acoustics in their lives. Listening Within the Ocean summarizes these important discoveries, providing both a valuable resource for researchers and enjoyable reading for non-professionals interested in marine life.
Book Synopsis Ethology and Behavioral Ecology of Mysticetes by : Christopher W. Clark
Download or read book Ethology and Behavioral Ecology of Mysticetes written by Christopher W. Clark and published by Springer Nature. This book was released on 2022-07-02 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, an international team of leading marine mammal scientists, with a remarkably diverse set of backgrounds and areas of expertise, lead you through a synthesis of current knowledge on baleen whales. Baleen whales are the largest animals ever to have lived on this planet. They also have the lowest and most intense voices on Earth, most likely evolved to take advantage of ocean acoustic transmission conditions so as to be detectable across ocean basins. Some baleen whales can live to be 150-200 years old. They migrate many thousands of kilometers between feeding and breeding areas. They produce songs and calls that serve as behavioral foundations for establishing, maintaining and expanding their cultural identities. To conclude that we know the behavioral limits of these large brained, long-lived animals would be naïve. As baleen whale scientists, we are still beginning to comprehend the enormous complexities and natural histories of these remarkable animals. Today, the fact that whales sing is known throughout much of the world. This awareness started 50 years ago with the publication and popularization of a collection of humpback song recordings that motivated research into baleen whale behavioral ethology. In this book’s chapters, a reader’s experiences will stretch from learning about baleen whale laryngeal anatomy associated with their different voices to learning about the vast ocean areas over which their voices can be heard and the emerging complexities of their culturally defined societies. These are accompanied by chapters on the fundamental ethological contexts of socializing, migrating, and foraging. Two common themes permeate the book. One theme highlights the phenomenal increase in scientific knowledge achieved through technological advancements. The other theme recognizes the impacts of human-made activities on ocean acoustic environments and the resultant influences on the health and survival of individual whales and their populations. Although the book is intentionally ambitious in its scope, as scientists, we fully recognize that baleen whale science is still in its infancy. Many profound revelations await discovery by cohorts of young, multi-talented explorers, some of whom are stretching their wings in this volume and some of whom are reading these scientific stories for the first time.

Available in PDF, EPUB and Kindle. Book excerpt: "On April 30, 1994, Public Law 103-238 was enacted allowing significant changes to provisions within the Marine Mammal Protection Act (MMPA). Interactions between marine mammals and commercial fisheries are addressed under three new sections. This new regime replaced the interim exemption that has regulated fisheries-related incidental takes since 1988. Section 117, Stock Assessments, required the establishment of three regional scientific review groups to advise and report on the status of marine mammal stocks within Alaska waters, along the Pacific Coast (including Hawaii), and the Atlantic Coast (including the Gulf of Mexico). This report provides information on the marine mammal stocks of Alaska under the jurisdiction of the National Marine Fisheries Service"--Preface.

Book Synopsis The Soul of All Living Creatures by : Vint Virga, D.V.M.
Download or read book The Soul of All Living Creatures written by Vint Virga, D.V.M. and published by Crown. This book was released on 2014-07-08 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: As profiled in the New York Times Magazine… Based on the author’s twenty-five years of experience as a veterinarian and veterinary behaviorist, The Soul of All Living Creatures delves into the inner lives of animals – from whales, wolves, and leopards to mice, dogs, and cats – and explores the relationships we forge with them. As an emergency room clinician four years out of veterinary school, Dr. Vint Virga had a life-changing experience: he witnessed the power of simple human contact and compassion to affect the recovery of a dog struggling to survive after being hit by a car. Observing firsthand the remarkably strong connection between humans and animals inspired him to explore the world from the viewpoint of animals and taught him to respect the kinship that connects us. With The Soul of All Living Creatures, Virga draws from his decades in veterinary practice to reveal how, by striving to perceive the world as animals do, we can enrich our own appreciation of life, enhance our character, nurture our relationships, improve our communication with others, reorder our values, and deepen our grasp of spirituality. Virga discerningly illuminates basic traits shared by both humans and animals and makes animal behavior meaningful, relevant, and easy to understand. Insightful and eloquent, The Soul of All Living Creatures offers an intimate journey into the lives of our fellow creatures and a thought-provoking promise of what we can learn from spending time with them.

Download or read book The Gray Whale: Eschrichtius Robustus written by Mary Lou Jones and published by Academic Press. This book was released on 2012-12-02 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gray Whale: Eschrichtius robustus provides an introduction to the understanding of Eschrichtius robustus or the gray whale. This book explores the life processes, reproduction, and growth of large cetacean populations. Organized into four parts encompassing 25 chapters, this book begins with an overview of the gray whale evolution, fossils, and subfossil remains, range, and systematics in historical times. This text then presents the historical of gray whale exploitation and the economic importance of these whales to humans. Other chapters consider the gray whale migration, abundance, and seasonal distribution in the wake of the California population's recovery from depletion. This book discusses as well the methods used in shore-based censuses during migration and in aerial surveys of gray whales taken on their winter grounds. The final chapter deals with some innovative approaches to the study of free-ranging cetaceans. This book is a valuable resource for anthropologists, paleontologists, biologists, and naturalists.
